School of Refresher Flying (SORF) Manby in the late 60s:ten bob into the coffee swindle gave you a JP4 for the weekend. I remember 'borrowing' one to take to Coltishall but, because Colt decided to close early that Friday, arranging to go to Norwich where I landed on a green from ATC because JPs were UHF only.
Who would authorise that nowadays!
